To all whom t mayconcem;

Be itA known that l,- EMIL Bonanni, a

, citizen of 'theUnited States, anda' resident ofNew York, in the borough of Brooklyn, county of Kings, `and State of New York, have invented certain new and useful Improvements in lDoor-Checking Hinges, vof which the following isa specification.

This invention relates ,to door-.checking hinges,k and more particularly vto that `type in the operation of whicha checking liquid is used, when the partsv are moved relatively to each other. The object of the invention is to provide certain improvements .in dQQrchecking hinges which tend to simplify the l construction, increasethe efliciencyvand improve the appearance thereof, and the salient featurev ofthe invention consists -in forcing achecking liquid from the interior of one. barrel to the interior of Ithe .other bari-eh'lthrough -a web or connecting member connecting the barrels, andto so regulate the {low-of t-he checking liquidv that 4an eliicient checkingaction results.

This improved .doorchecking hinge 'is usually applied to the doorrin the same manner that a double-acting ora single-,acting spring butt-hinge iis applied, namely, be

I tween the doorand its frame, and .has the general appearance of a double-.acting spring butt-hinge, Aor of a single-'acting spring butt-hinge, as the case may be, or, inthe case kof a hinge havingsurfac'eflanges it may be fastened ltothe surfacesof the door, and .they adjacent door-casing respectively, but in leither case it obviates ,the ineleg'ant and cumbersome appearance ofthe door-checks now commonly usedat one. or the other side of the top of the door or doorcasing, and the use of the more or less unsightly jointed arm. A furtheradvantage of this improved door-checking hinge isthat it can be provided with `a self-contained spring or springs for automatically closing the door, or without the same asmaybe preferred, and can also be applied withgreat kfacility to swinging doors,.so as ytooperate in connection with the well known ynonchecking types of [double-acting spring- :hinges which automatically restore thedoor to closed position-after beingopened, While the concurrent use of the improved checkinghinge with the spring-hinge prevents the sometimes dangerous quick closing and also the to-and-fro vmovement or flip-flapping in swinging doors, before theyvcomc to rest in their closed position. Y,

yThe invention is contained in the embodiments shown in the accompanying drawing and will be more fully described here inafter and linally pointed out in the claims.

'Above the upp'er collars B2fan^enlarged 'upperjcollar 33;"{also preferably inade` kintegral with Vthe vshaftf28 and' adapted to eXtendover the upper edge ofthe .barrels sofas to be seated'there'on, isA arranged. v Below the collars 30, the `s'haft'28 is providedwith. a 4wing .48' ofv practically in'adel integral withV the'ysha'ft r28, *said wing havingfface's .46Jand 47 which are preferably radial with'the vcenterfo'f.the shaft 28.2f The lwing 48 'extends downwardly from the'coljlars() tog'the bottoni of thebarrel'fll, the froundedback'49 of .the wing 48 being? convcentric -with"theshaft 28 and being' finished,

Within the interior of the barrels 11and 12 and rigidly secured thereto by screws 55 or other means or cast integral with the barrels 11 and 12, is an obstructing wall or battle 56 which has faces 57 and 58 which are preferably radial to the center of the shaft 28 Aso as to aline with the faces 46 and 47 of the wing 18. The inner surface of the obstructing wall or baffle 56, adjacent to the shaft 28, is concentric with and finished to a working fit with the shaft 28.

The enlarged upper collar 33 of the shaft 28 is provided with a socket 36 which extends downward and preferably into the collar 32, andalso preferably has a perforation 34 passing diametrically therethrough. Between the enlarged upper 'collar' 33 of the shaft 28 and the ear 40, a spacing washer 38, having a central perforation, may be arranged, said spacing washer 38 being inserted merely for convenience in assembling the parts of the door-checking hinge. The ear lOof the 1leaf 13 has a perforation i2 passing diametrically therethrough. A vertical pin-shaft 37 having` diametrical perforations and 39, which register with the perforations 3st of the collar 33 and the perforation 42 of the ear 40, extends downwardly through the ear L10spacing washer 38 and into the socket 36 of the collar 33. When the perforations respectively of the pin-shaft 37, ear l0 and collar 33 are in register, pins 35L and 41 are inserted therein and one method of securing a rigid connection or locking of the leaf 13 with the oscillating shaft 28 to simultaneous movement is thereby disclosed. By this connection, the movement ofthe leaf 13 causes the movement of the oscillating` shaft 28 in the barrel 11. The leaf 15 is connected in like manner tol the other oscillating shaft 28. Ball-tips or other shaped tips may, if desired, be attached, for instance, to screw-threaded proi. jecting ends 37ZL of the pin-shaft 37.

A suitable controlling-screw 60, shown in 2, or a similar device, may be inserted into a perforation 61 of the lower edge of the web, which screw is preferably provided with a packing to prevent escape of liquid, as shown at 62. This screw may be located at any suitable point of the connecting-plate or web 10, provided it shall intersect the channel 25, for the purpose of4 varying the cross-sectional area vof the said channel 25,

and therebyv permitting af further control of the volume of flow of the checking-liquid from one barrel to the other barrel, if found necessary in the case, for instance, of specially heavy doors or in case of thinning of the checking-liquid in very hot weather, and at the same time also thereby further controlling the checking speed of the doorchecking hinge, and finally also thereby providing a means for increasing` or diminishing, or for draining or renewing the supply of checking-liquid, as may prove to be desirable.

The parts coperating with and moving within the barrels 12 of the different embodiments simultaneously with the leaf 15, are exactly the same in construction as hereinbefore described forl barrel 11 and leaf 13, aswill be clearly seen by a comparison of the right-hand side with the left-hand side of the view shownl in Figs. 2, 5 and 6.

riChis door-checking hinge can be produced -without spring-power for closing the door; the embodiment shown in Figs. 1 to 6 is 1ntended only for use on. doors which are automatically closed by one or more additional double-acting spring-hin ges, or by some similar door-closing device, and is designed to check the momentum of such doors when closing, and to prevent them from swinging to and fro before coming to rest at their closed position, which action is termed flipflapping.

Referring more particularly to Fig. 5, in which a horizontal section is shown, it will be noted that the leaves 13 and 15 are parallel with and substantially contact with the web 10 of the .door-checking hinge, as is usual in double-acting spring-hinges.

' Then the leaves 13 and 15 are in this position, the extending finger-portion of the shaft 28 is in proximity to the surface 57 of the obstructing wall or bafiie 56 of the barrel 11, and it then has its opening 51 in register with the opening 26 of the channel 25, and similarly the other extending finger-portion 50 of the other shaft 28 in the barrel 12 has then also its opening 51 in register with the opening 2T of the channel 25. W'hen the parts are in this position, the checking liquid which is placed within the channel 25 and the barrels 11 and 12, between the face 57 of the baflie 56 and face i7 of the wing 4-8, will readily find its own level in the two barrels, and by reason thereof approximately equa-l portions of the liquid will collect in each barrel, and the channel 25 connecting the barrels 11 and 12 is then unobstructed.

Referring new more particularly to Fig. 6, the leaf 13 of the barrel 11 is in a position corresponding to the open position of the door, namely, in position at right angles to the position of the same part shown in Fig. 5. 1t will be noted that by the movement of the leaf 13, the shaft 28 is correspondingly springs free to latch the door or hold it in tionate in energy to the speed or yforce with which the door is opened, and correspondingly accelerates the movement ofthe checking-liquid into the greatly increasedspace in the barrel 11. .f

W'hen, however, vthe door closes under the 'spring-pressure of its independent doorclosing device, or for instance, under the pressure of its self-contained door-closing spring, if any, the increased volumey of checking liquid in the barrel 11 is forced thereby to return again through the channel 25 to the other barrel 12 at the other side of the hinge, at a speed and pressure proportionate to the spring-power of the said vdoor-closing device and the speed of liow vof the checking-liquid through the channel 25. This takes place until the eX- ten'ding finger-portion 50 of the wing 48 eX- tends over and closes the opening 26 of the channel 25, whereby an additional and more or less positive check is given at this point against the lfurther closing of the door by reason of the fact that the flow of theV checking-liquid is prevented by the stopping of the channel 25 by the end portion of the linger 50. This, however, in practice is soon relieved, probably by a certain leakage of the checkingliquid under pressure between the parts, or by the movement of the liquid upwardly probably against the more 0r less compressed air in the barrel. After this secondary checking action is overcome, then the registering of the opening 51 with the opening 26l of channel 25 gradually takes place bythe continued movement of the shaft 28 and finger 50 under the pressure exerted by the additional independent doorclosing device or by the self-contained springs, if any, whereupon the liquid passes through the channel 25, and the liquid may then again equalize in the barrels 11 and 12 and channel 25. By the use of this checking action, the door closes silently, and in the case ofv a swinging door withoutany to-and-fro movement, and this relief1 of the checking-action at or near the closing position of the door, leaves the independent door-closing device or the self-contained closed position, as the case may require. It

is clear that on the movement of the leaf 15 a like sequence of action takes place.

Through the coperation of the parts and the reciprocatory movement of the checking liquid from one barrel or container to the other barrel or container through the connecting-channel 25 of the web or connecting member 10, as the door is opened `to one side or the other, a very efficient door-checking hinge is produced, lwhich is of great simplicity and durability in all its parts and which has an elegant appearance.A

Changing a doable-acting door-checking Mage 250V a single-acting door-checking hnge. y

Double-@ewig door-checking hinge with self-contained spring.

To show that the invention, as embodied in'this door-checking hinge, can also be arranged to coperate with self-contained springs forautomatically closing the door, the embodiments-shown in Figs. 10 to l2are shown, in which a pair of these double-acting spring-hinges can be used without any additional door-closing device or springhinge. i

In Figs.v 10, 11 and 12 a combined doubleacting door-check with a spring-hinge is shown, in whichl the door-checking: portionis preferably arranged uppermost, and the hinge-portion is preferably arranged lowermost. kIn this embodiment, the yleaf 70 has three lears 71, 72 and 73, and the leaf 74 has three ears 75, 76 and 77. The leaves 70 and 74 have the usual screwopenings 78a for fastening purposes. Between the ears 71 and 72, the barrel 78, which is preferably made integral with the web, 85 of the door-checking portion, is seated, said ybarrel 78 inclosing the oscillating shaft 28, with its finger 50, wing 45, packing 29a, and collars 30, 32 and 33. rllhecollar 33 is keyed to the ear 70 by the vertical pin 37 and horizontal pins 39 and 35a. The washer 38 isk interposed between the ear 70 and collar 33. All these parts are arrangedin the same manner and have the same sequence of action as shown in the embodiment illustrated in Figs. 1 to 6. A similar mechanism is arranged within the barrel 80 of the vdoor-checking portion which barrel isalso preferably made integral with the web 85. Tips 17,18, 19 and 2O may also be suitably applied. f

Between the years 72 and 73, a preferably lll@ separatebarrel 81l of thespring-hingef por- Jtion is seated, and betweenthe correspond-u ring ears 7 6 and 77 a' similar preferably sepi arate barrel 82 is seated. The 'barrels 81t and 82, as also the barrels 80' and 78,; are connected with a WebS'commonl to all the barrels. This iveb- 85 has a channelv 25 for.

the checking-liquid therein,- iv-hich channel 25 connectsv the barrels 78 and'80,. and`l through which 'the checking-liquid operates in the manner describedin connection- With the embodiments particularly described-heretofore and shoivn in Figs-1l to 6.y A governingk device consisting in this case preferably of a rotatable plug 87 with achannely 88 is interposed in the path ofthe channel 25,` and the movement of the plug in'respect to the channel causes the channel 25 to be more or less opened or closed, depending upon Whetherl the channel 88 is desired tobe inV or not in registrationcomplete or partial with the checking liquid-channelv25. This isfclearly shown inFig. 12, and the plug. 87

may be readily operated byfthepreferably slotted'v heads 87a, having al slot 87"'.

This auxiliary barrel 151 has a closed bottom 152 and an open top 153, which is engaged by a screw-threaded plug 154. This barrel 151 is so arranged in respect to the barrel 141 that it may readily coperate therewith, and in the embodiment shown in Fig. 19, the connecting member 155, which conforms substantially' to the web 10 of the embodiment shown in Fig. 2, for instance, is arranged. The lower part of this connecting member 155, or web, if it is desired to be so called, is provided with a checking-liquid connecting-channel 25 which brings about communication between the interior of the barrel 141 with the interior of the barrel 151. A suitable screw-plug 156, substantially like the screw-plug 60 of Fig. 2, may be provided for the same purposes as the screw-plug 60. The operation of the shaft 28, with its wing 45 and finger 50, is exactly like that already ff described, and it forces into the auxiliary barrel 151 or sucks out therefrom by means of the channel 25, the checking-liquid and in all respects operates in the same way as the embodiments in Figs. 1 to 6, with the exception only, of course, that the embodiment of Fig. 10 is only capable of operating in one direction.

v The operation of the embodiments of Figs. 21, 22 and 23, is substantially like that of Fig. 19, and more particularly also like the embodiment in Fig. 10, being, however, only of a single-acting character, whereas the embodiment in Fig. 10 is double-acting.

In the embodiment shown in Fig. 21, the door-checking portion embodies the same elements as that of Fig. 19, and the lower portion again has the adjustable springholder 93, the pintle 90, the barrel 81, the, coil spring 95, the fixed spring-holder 9G, the ears 72 and 7 3, and the tip 19, and in Fig. 23 the leaf 140a has openings 162 for the fastening screws, as also the leaf 140b has openings 160 for the fastening screws, clearly shown. It is clear, however, that the springhinge portion may be arranged on the upper part and the door-checking portion at the lower part, or that other suitable combinations may be made in the form of placing one spring-hinge portion between two door-checking portions, or one doorchecking portion may be placed between two spring-hinge portions.
